New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG. We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

Why Am I making less that before-Market Trends Explained!!
Hi folks recently I had been following reditt and it's pretty funny to see people jumping into crypto currency mining without understanding the basics and how markets in general work.I would like to answer some of these questions here Q1.Why is Nicehash payment soo low compaired to couple of months back.Even after bit coins has recoverd in value since A- 4 Reasons 1.Sudden Influx of new miners into nicehash and into the mining game in general due to the bull run (up market) in crypto currencies that we say in the past couple of months .On the day A Video on NH by Youtuber austin Evans was relseased we recorded a sudden increase in the global hashing power,which was never seen before .AFTER EVERY SUDDEN RISE THERE IS A SUDDEN FALL.-economics 101 2.Remeber NH doesn't mine a single coin it mines algorithim that can be shared by multiple coins and you are generally paid based on several factors like Btc/$ rates,current rates of other mined currencies like ZCASH (equihash),ETH (daggerhashimoto),etc and most importantly the SUPPLY (no.of gpus pointed at HN) Vs. DEMAND (No.Of buyers buying the hashing power coming out of the gpus).Since more people discoverying about the eazy 1 click "Sell hashing power" feature on NH and have no idea about the complicated "buying hashing power" section leads to more SUPPLY less DEMAND = LOW PAYOUTS 3.On NH You are only decrypting a gpu supported algorithm which is shared by many coins,all of these coins also known as alt coins are pegged against Bitcoins which is inturn by most people pegged against the dollar.So the change in the value of any one of these factors ie.Hashing PoweAlt coin demand and difficulty/Bitcoins value/Dollar fiat currency value can change your daily payout. 4.zcash,eth and other gpu mined coins still didnot fully recover to the value it had a couple of monts ago its recovering very slowly 4.Low Demand from buyer of hashing power due to uncertanity in the mining world due to Changes been made into the bitcoin system on August 1 August 1 Uncertanity = Scared Market = Low demand =Bear Run (down market).Read more only about that Note- Nicehash payouts has increased around 30% as bitcoin rates to dollar rate had also shown a similar up trend,since you are paid in mBtc or bitcoins in general never compare your NH Bitcoin payments with fiat currency ($€£¥,etc) because that $10 that you hold in btc now can be $30 in the future if bitcoin rates rises in the future.Happened in the past with my friends who sold a lot of mined bit coins in 2013 for mere dollars ,the value of those bit coins are now in millions.Then again if Btc crashes your held $10 in bitcoins can fall to mere 0. Since sometimes history repeats holding mined or bought btc for some time is more profitable than selling now.The price of btc will standardise one day if more and more people start adopting btc payments and there will be marginal profits to be made then by trading or mining coins (eg .modern fiat currency trading or gold trading).Again it's just a speculation based on historical analysis. Q2.When will my GPU's become FREE A1.NOW,ie.if you scored your cards before gpu prices skyrocketed if you sell them now the money you made till now by mining will be free+extra premium for the cards.Mosr cards come with 3yrs warrenty so that helps with the sale Your GPU ROI is paid the day you make 40% of what you paid for your gpu by mining ,the other 60% of the ROI can comes from selling your cards.These days even used cards are sold for 110% the price of the Box price as new cards are sold for 150-200% the original price. Price of mining/gaming grade GPU is at all time high now even though Gtx 1070/1080 and Amd RX cards are nearing the 2nd half of there life cycle .We see new faster and cheaper cards every 2 years or so.so the price of your mining cards will keep going down from now on as new surplus stock of these cards will be out in August-September and New mining cards are coming out around September aswell.Better invest in new cards to stay ahead in the mining game. Q3.They why dont You sell your cards You are Mining right? A1.Im under the assumption that Bitcoins will one day touch $5000 mark one day.so what ever I'm mining now if compared to the my investment and the current market I will be making my ROI in 1year plus or maybe never as difficulty of mining increases every now and then but I think bitcoin is a very functional form to currency it can add a lot of value to our society (FUN FACT-Do you know private bank can print free money,Google it up) bit coins patches all the problems with out current centralised money system making us slave for the govt.Bitcoins is the future of money So if i follow this single idea of bit coins getting to $5000 one day my $100 is btc today will be around $280 approx. Or could be $50 . YOU CAN NEVER ACCURATELY SPECULATE IN AN OPEN MARKET.So Stop fantasizing about getting rich quick by mining if you can do it then so the guy living next door.Have trust on crypto coins use them to buy stuff that helps making the whole currency valuable and your coins as well. Q4.Mining Via NH vs Mining Altcoin directly vs Mining bit coins vs trading coins. A1.Mining Via NH-Hassle free,Paid in btc,auto switching,optimised and stable than all.Saves a lot of time=More hashing time=more earning. You do pay a small % as frees but that's negligible compared to the time it saves. Mining Directly - Hasselous,manual setup,non noob friendly,you get to keep all the profits plus you are mining an alt coin directly so if your cards are good at one or two coins then more profit here plus you are look the market and mine anything that high today Or would increase in a couple of days and sell later for a huge profit.Smart human auto switching makes you more money than NH. It's more fun but takes more time. Mining Bitcoins-No You can't,too difficult to mine btc with gpu the Chinese got a lot of the bitcoin mining mega farms. Trading coins-Always profitable bought bit coins last month,sold yesterday making a sweet $3000 profit in 3 weeks.Buy now and sell later will always make you some profit since bit coins are finite in number like gold,you can't create new bit coins out of thin air.so if bitcoin catches and more people know about it it's value can go though the roof. Q4.Any better way to mine? ASIC vs Bitman miners vs Gpu rigs A4. Now folkes asic miners (bitman miners) eta can mine better than any gpu in the market they are specifically built for mining a certain algorithm(coin) ie.No auto switching .So if the coin falls in value you are left with the most advance and expensive door stopper in the world.No one would touch the hardware and it's value could be zero in a day.Usually these miners loose all it's value in 1 yr or 2 as difficulty increases Not so with GPUs.Say I have 2 gtx1070 and a gtx 970 bought for say $1300 (same price as a asic miner) mining 24/7 and I earn some bit coins (surely a bit less than mining on an asic) but again next year say all my cards become unprofitable by mining then I'm still the owner of with a super advance and a very expensive gaming rig on which I can do multiple display and also multiple instance of gaming. I can sell the 1070 and 970 to a gamer with 2yr warranty on those cards and I can make the reminder as gaming never falls out of favour.Remeber these cards can still decrypt other stuff like Wi-Fi passwords and physical stimulation and calculations in minutes,that's how hard mining has got and difficulty will increase overtime. Q.Any suggestions ? A.I can share my plans Gameplan 1=Buy Newer cards quick in September ,Enjoy higher mining payouts,others will follow,mining hardware increases in price,then market crashes for sometime,you made your money,sell your cards for 100-150% the original value.Live happy every and after Gameplan2-Buy bit coins today,wait till the prices reaches another all time high ,happens every year,Sell and don't forget to live happy every and after, A happy man is some one with no money to worry about. -My Father said to me the day I started mining.
TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party. Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this? Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?" Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here. Now, why are these changes so large? A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010. In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon. In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips. In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race. ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty. The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months. Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
I read that you can mine with a CPU/GPU, should I do so?
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase. And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
I get free electricity and I have existing hardware, should I still mine?
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
Should I buy an ASIC machine?
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
You are assuming your pre-order will arrive on time. (I do not think any first batch pre-order from any manufacturer has arrived on time).
All pre-orders are sold out for 1 Dec.
You are assuming your chips will run at 450Gh/sec minimum but many miners here will tell you their chips have been under performing.
Electricity cost have not been taken into account.
Shipping cost and time has not been taking into account.
Import Tax or VAT has not been taken into account.
Risk of downtime due to DOA or warranties has not been taken into account.
You are assuming the difficulty increase will be a constant 35% which is very unlikely because Cointerra with a team that has worked on some of the world’s highest performance CPUs, GPUs and chipsets for NVIDIA, Intel, Samsung, Qualcomm and Nortel has pre-sold an absurd amount of hash rate. Difficulty increase of 45% or more (which we have seen when a small player, KnC shipped their 1st batch) will be repeated commonly. This is only 1 company, imagine what the rest will come out with. I have failed repeatedly and so have many in estimating future hashrate. You wont be able to do better.
Even if you earn some profit, it will be < 15% and will probably be not worth your risk or your trouble. I can buy and hold XBT with no risk of losing them.
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case. The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
I understand I probably won't earn any money, I just want to do this for fun/hobby...
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
I want something with more omph and still do not mind losing money
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
Who are the manufacturers?
You can check out the manufacturers and their products below along with a calculator here. If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice. Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee. However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
Which pool should I use?
I actually do not use any of the pools recommended to the left because I think they lack features. My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap. Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me. BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised. All of them pay out transaction fees.
1- Primecoin is the First non Hash-Cash PoW Crypto-Currency.
"Primecoin is the first to show that a proof-of-work algorithm could exist to compute things other than cryptographic hash functions."
2- Naturally Scarce
Primecoin is naturally scarce (not artificially) -no hard limit and this is crucial for its long term continuity and its ability to adapt to market conditions.
According to the last estimations, the total supply is going to be ~55 Millions XPM. (peercointalk.org) You don't have to worry about inflation, neither facing blunt deflation (encountered in bitcoin/litecoin)
3- Very fast confirmations - 1min/block 4- Elastic supply
ING economist: "A bitcoin algorithm needs to be developed that smoothly matches money supply & demand"
This is hard-coded in Primecoin: difficulty going down gets corrected upwards because miners are encouraged to mine, having more reward subsidy.
When difficulty is dropping (i.e. miners leave the network), reward-revenue is recalculated upwards so that they come back in, ensuring the network security elastically vs price bumps.
5- Primecoin is sustainable
"Primecoin does not use a fixed cap money supply model like bitcoin as described in the primecoin paper, instead its mining output is associate with Moore's Law. It should have much slower drop of mining subsidy than bitcoin in the longer term (10+ years) thus much less affected than bitcoin in terms of risk of low security level. If Moore's law stops at some point then primecoin block subsidy would become relatively constant, rather than tending to zero as in the case of bitcoin (note though primecoin inflation rate is still tending to zero)."
"When the proof-of-work mint rate approaches zero, there is less and less incentive to mint proof-of-work blocks. Bitcoin is insecure."
"Primecoin has still good scarcity property similar to gold while network security is maintained without the need to raise transaction fee."
"Long-term bitcoin security relies mainly on transaction fees. Primecoin realistically would continue to have some subsidy long term, so is less reliant on transaction fees for security."
6- Primecoin is currently the “fairest” coin to mine
"The Primecoin algorithm is ASIC/FPGA hostile, and even GPU mining is not economically viable at the moment. While it is certainly possible to create specialized mining equipment, it is far more difficult and expensive to develop chips for high speed modular arithmetics. In contrast to SHA-256/Scrypt mining, those chips would also be multi-use and could be applied for other purposes after the next generation hits the market. In a sense, Primecoin is currently the “fairest” coin to mine, as it is purely CPU/GPU based. [...] Besides this, Primecoin already offers a number cloud mining providers, which inevitability will be the final stage in the specialized-mining-chip-race. For example, ASIC supplier KnCMiner recently announced not to produce mining rigs for household use anymore, as non-industrial grade power supply is not sufficient."
7- Primecoin can introduce new participants to the new digital economy
"In a Free Market, there's Free Will (and Creativity) as driver for Actions - and fundamentally Primecoin (almost philosophically) provides us with the ability/choice of applying our Ingenuity on Mining."
"With Primecoin, people who like to mine cryptocurrencies have a better choice to mine, to get more benefit out of the mining activity & environmental cost."
"Primecoin complements the goal here as it produces additional scientific value from the consumed energy. So people who like to mine cryptocurrency for whatever reason have a better choice to mine, to get more benefit out of the mining activity and environmental cost."
With Primecoin, you can actually and effectively Innovate and Improve on Mining Technologies and Techniques, on 2 lines: Hardware and Software. This is radically different from hash-cash PoW. In essence you have twice as much possibilities to earn revenues.
8- Proof-of-work cryptos will gradually transition toward energy-multiuse, ie providing both security & technological computing values. And Primecoin is the pioneer in this realm.
"One year after primecoin's public debut, the cryptocurrency designers are still focused on mixing hash functions with hash-cash proof-of-work, or finding ever more 'cpu friendly' proof-of-work; Primecoin's unique proof-of-work remains the first and one of the very few useful and actually interesting proof-of-work designs, that preserves the decentralization property of cryptocurrency."
9- Primecoin has anti-centralization features
Brute force hashing random numbers, under rigid guidelines(the more CPU, the stronger) doesn't work to mine primecoins - there's no known rules to find prime chains.
Elastic reward re-calibration, in real-time (reward gets immediately lower if difficulty would happen to rise)
10- Primecoin captures the Wasted Energy of Bitcoin's Algorithm - The mining is actually useful
"The reason why Primecoin-like “useful POWs” are the most promising is that, if the computations are useful enough, the currency’s “waste factor” can actually drop below zero, making the currency a public good."
"The innovative prime proof-of-work in Primecoin not only provides security and minting to the network, but also generates a special form of prime number chains of interest to mathematical research. Thus primecoin network is energy-multiuse, compared to bitcoin network. Primecoin is designed to sustain a prosperous mining market and high level of security, while maintaining good scarcity property like gold. Primecoin also processes payment transactions 10x faster than bitcoin network."
"Primecoin's proof-of-work is still pretty much the only alternative proof-of-work in production other than hashcash. By alternative proof-of-work, is meant alternative proof-of-work consensus. Interestingly, Primecoin also tries to address bitcoin's energy problem, from a different angle. In a free market, there is bound to be [the] coexistence of energy intensive currencies and energy efficient currencies, meaning, people have free will to consume energy to produce currency for example, mining gold. So Primecoin would demonstrate, such energy consumption can be made energy-multiuse, while preserving the critical decentralization property."
11- Primecoin has direct by-products
"Bitcoin hashing or mining provides no meaningful by-product whereas Primecoin delivers the chains of prime numbers. Primecoin is the first cryptocurrency with such property."
"Prime numbers are very useful. They are important in cryptography, and used in many encryption systems. The larger the list of known primes grows, and as the value of the numbers increases, the security of encryption methods utilizing them improves. Understanding prime numbers is also very important for high level mathematics, physics, and engineering. All non-prime numbers can be constructed from two or more prime numbers, yet a prime number itself cannot be created from any other number. Prime numbers are the building blocks of math. The more we understand about primes, we more we understand about mathematics. The more we understand about mathematics, the more we understand about the universe, and everything in it."
"For example, Primecoin provides financial incentive to these math research (e.g. research about the twin prime conjecture), if your theory advancement can provide a better mining algorithm for Primecoin mining. Twin prime is a special case of bi-twin chain. A bi-twin chain of length two, that is."
"With Primecoin, it's possible to do a proof-of-work consensus other than hashcash and have potential math research along with the fact that FPGA / ASIC development incentive may lead to problems being solved that have never happened before. It's possible, when you have ASIC primality testing chips, the computation capability in these fields would make a giant leap. That could also indirectly help theoretical research."
"Primecoin has delivered. It now holds 5 out of 21 world records in simultaneous prime numbers."
2 potential direct applications of the prime chains from Primecoin network:
Banking on Prime Numbers The prime number chains discovered by the Primecoin network may ultimately make RSA Encryption - and therefore banking in general - more secure by contributing longer prime numbers to use for RSA Encryption; the longer the prime number, the more difficult it is to "break" the encryption.
Hardware Testing & Innovation Since the early days of computing, programs for discovering prime numbers have been developed as a way to test new hardware These by-products include improved computer processors and hardware components, which can be applied to improve computer models used in the science, medical, and engineering industry.
12- Primecoin has been developed by Sunny King, one of the most talented crypto-technologists of the rank of Satoshi Nakamoto
Sunny King along with his team continues to grow Primecoin network and is currently developing a Sidechain technology for Primecoin, that is a common infrastructure to make it easier for developers to create decentralized and distributed data applications (of the sort of: namecoin, storj, peershare, datacoin )
Bitcoin, for all intents and purposes is the winner in the crypto space, for now. It has an enormous lead in every category that I would judge a crypto-currency / payment system by. That is not why I’m here, 1st place does not matter at this time, we’re fighting for 2nd. Bitcoin(and now SCRYPT coins) has a few issues that do not make it 100% ideal for a digital currency. Although I think that bitcoin is the future (at least in the near – midterm), it is not perfect. The problem, as many people here know, is the centralization of mining. The internet was created as a distributed system to defend itself from attacks. Hub and spoke models are being replaced by distributed networks as they are more resilient. Transmissions can route around damage instead of crossing a central hub which can be damaged, halting communication / transportation . This gives crypto a huge leg up over traditional fiat and it is also why Vertcoin is the superior #2 coin in the crypto space. Here’s an image of a hub and spoke vs distributed network. Hashing power gives a false sense of security. We hear it all of the time..ASICs increase network security as it defends the network from outside attacks. This is true, to a certain extent, but is also utter bullshit. ASIC technology, at this stage in the game, gives a massive first mover advantage. Chip makers can dominate a network. Scrypt coins are at the mercy of KNCMiner at this time and then whatever companies end up following them. For a fraction of the market cap of some of these coins you can have a chip designed and mass produced in China. Scrypt miners who now totally lack control over their mining profitability hope to receive their shiny new ASICs before difficulty is driven through the roof. We saw this with Butterfly Labs when everyone received their “money printers” well after the time they became worthless. Central Points of Failure When networks become centralized they contain points where damage can be inflicted. Crypto-currency networks are dependent on miners to process transactions, when the amount of actors in transaction processing is limited our precious technology begins to resemble the established banking system that many of us dislike, sure it is still more efficient, but it becomes open to damage and corruption. “Power corrupts, absolute power corrupts absolutely.” Resisting centralization is also resisting future corruption. We must resist, and remain open to adapt via Hard Forks whenever necessary. Software can be molded to fit the circumstances – let’s remain on the cutting edge and ensure a robust and distributed network is maintained. Why Litecoin is a shitty Alt Blockchain. Litecoin, although it has been a fantastic investment for those who got in early, is about to become a worthless coin. Litecoin has accomplished very little in its tenure as the #2 coin. The only advantage I can see is that up until this point it has maintained a distributed network, supported by GPU miners across the globe. Sure it’s block rate is faster but that point becomes irrelevant. Litecoin Developers have failed in their duty of maintaining a viable backup blockchain to bitcoin. That’s all it ever was and now, with the pending centralization via ASICs, it will become open to damage and corruption, and will no longer hold its place as a viable Alternative to Bitcoin. Hundreds of Millions of Dollars are at stake, Now Litecoin is valued at nearly $300 million USD. A huge sum and this is with what I believe to be a very suppressed price of bitcoin. The Litecoin mining community will soon experience a rapid decrease in numbers as their GPUs are no longer profitable to mine with. We, Vertcoin, are the logical place for them to point their rigs, and join our community. Our network will become much more robust in a massively and fairly distributed fashion. We’re currently valued at 1% of Litecoin! 1 lousy percent. We’ve got a lot of room to grow and a lot of work to do. What We Can Do Getting merchants to accept Vertcoin is great, but it is also very difficult at this time. The value proposition isn’t there. With bitcoin we’ve got a large community of people backed by $6 Billion of wealth, and we like to spend. That’s a huge difference compared to our little $3.4 million VTC. Merchants will come en emass once our value warrants it. Our community is made up, for the most part, of Miners. I’m not a miner myself, I’m an investor. Investors are required for VTC success, mining and spending doesn’t cut it, the increase in supply and the auto-dumping by miners will end up destroying us before we even fully get out of the gate. Spread the word, support your mining operation by also buying on exchanges, not selling. Partially mine other coins, sell them, and buy VTC. Buying pressure across the exchanges is absolutely required for us to become a viable alternative and Litecoin competitor. www.helpareporter.com is a site you can site up for, for free, to receive emails from reporters looking for help on their new articles. I recommend signing up and sharing your expertise (and give VTC a shoutout) whenever it makes sense to. Our Development Team is strong, our community is constantly growing, and the centralization of SCRYPT currencies is in sight. Let’s do what we can to make Vertcoin a Litecoin competitor, the Alternative to bitcoin’s blockchain, and a possible future contender as the crypto King. Disclaimer: I hold several VTC and my near term marketcap target is $40-60 million 2nd Disclaimer: I woke up hungover and started writing.
_trendspotter at /goodcoin brought up an evaluation we can use to at least measure, rate, or review cryptocurrency based on how good they are. Here at scamcoin I think we should come up the evaluation on how BAD these guys are, just the opposite of his scale. I suggest you should use this guide also as a reference when you are looking to INVEST in a cryptocurrency. If you guys have suggestions/ideas feel free to bring it up. It is no way being objective but at least we can try. Power to the people. The problem I still trying to sort out is to weight some features properly: Anyway, the proposal Scammy Scale Rating with simple Yes or No: 1) NOT de-centralize & Not open source 2) No open-source at the release 3) "Public offering" period where one has to pay to mine early 4) No fair launch announcement, unreasonable pre-mine and/or any insta-mine 5) Extremely low starting difficulty 6) No adoption among merchants/vendors/region/country. 7) No trading at big exchanges (e.g. not on BTC-e) 8) Not offer any new feature. Clonecoins or Litecoin forking 9) Bad developer supports, lack of community or forum 10) Releasing bad software that impedes certain users from using/mining the coin. Or "faulty" start, "nodes" problem 11) Slow transaction or confirmation time 12) Short block time when mining 13) Inflated to billion of shares/coins or unreasonable supplies 14) Pseudo mumbo jumbo descriptions of the cryptocurrency 15) Poor official website, hastily done 16) No anonymity support (no Zerocoin implementation) 17) Weak security, vulnerable to 51% attack (No POS or Proof of Stake) 18) Aggressive marketing campaign, hijacking forums and threads, tons of giveaways and faucets 19) Bloat future blockchain, e.g. 2GB-60-100GB wallet you have to update even though your wallet has 2 ABC coin. 20) Weak to ASIC,GPU,FPGA miners, BotNet, or does not give everyone at least a fair chance to mine 21) Reversible transaction -- Not sure if I should leave this out 22) Low mining profitability (vs mining Bitcoin) 23) Designed to be inflationary nature 24) No interest rate of earning coin per year 25) No Multi-hashing algorithms 26) Recent release 27) Pump and dump announcements (Twitter, Facebook, subreddits or forums) associated with said cryptocurrency 28) "Rebooting" the coin, or "coin makeover" to make it fair mining/distribution again 29) Shady developers' history and/or shady major fund backers' history/intention 30) No trendsetter or no noise around the web. Use Google Trend as a way to monitor buzzes. Example:http://www.google.com/trends/explore#q=quark%20coin%2C%20bitcoin&cmpt=q 31) Not much liquidity and being dependent. How dependent of that alt-coin to that of Bitcoin? Meaning, if Bitcoin goes down 20% in value, will it also dip 20% or more? 32) Unknown or less coins' volume/share percentage jumped through the roof while other known coins have modest or small gain. Example: SexCoin jumped 1200% in a single day while Bitcoin gained 3.8% 33) "Pay first, deliver product [Bitcoin 2.0] later" - essentially investors are convinced they have to pay first in USD/bitcoin because they are promised by the developers/company to have an "EARLY START" or "EARLY SHARES" or "PRE-SHARES" on the best next-generation "Bitcoin 2.0" coin that will make Bitcoin obsolete and will be the next biggest thing in the universe. Except for the part where "the biggest thing in the universe" is nowhere to be seen. 34) Interoperability 35) Purely Proof-of-Stake (POS) coins We then can further breakdown and give weigh point to each feature and start ranking them. For example: CrappyCoin : 10 yes, 15 No. A simple solution is each Yes = 1 point and each No = 0 point. However, subjectively some features should be weight more than others. I should point how to merchant adoption and trading/buy/sell at big exchanges, multi-hashing and fair mining for everyone should be scored higher. It goes hand-in-hand with its release date. Feel free to discuss.
A FPGA opensource miner has just been released running at 80Mhps but at a cost of $585. The efficiency is stated below quoted from a post in the thread.
At 80 MHps, I will need at least 3 of these to achieve a single 5830 hashrate. That is $595.-x 3 = $1785.- at full price, vs. $190.- for the 5830. Giving the 5830 is consuming $11.- a month in electricity, and assuming this board will consume zero electricity, it will take more than 145 months, or 12 years to recover the investment, always comparing to a 5830.
Apologies but no more development information will be posted. I've been offered a 25% share from someone that owns 2 FPGA clusters. If you haven't seen that type of hardware before think a 156 FPGAs per machine.
From those posts what we can understand is that the factors that affect FPGA now are high procurement cost, low running cost and ease of scalability . What this means is that with the increasing total hash rate of the network (30Ghash/day last difficultly adjustment) the question becomes when would the difficulty render GPU inefficient in contrast to running cost? Remember to take into account FPGAs are usually run in clusters and even though it would not be beneficial to buy one outright, those who have access to FPGA are the first movers and eventual dominant forces of the mining market. Of course, in the end, ASIC is where it's at. Anyone? =D Edit: read more stuff, added info.
First I'd try to figure out if the software was merely using access denial or encryption. With access denial, the data isn't encrypted, but the software won't show you the data without the password. For purposes of criminal forensics, you're not allowed to change the data in any way for it to be admissible in court, but getting access to the file before you have a password can often be helpful. To figure that out, I'd just look at the file in a hex editor; if I could read it, it wasn't encrypted. The next easy step is to scan the program for cryptographic constants; these are things like s-boxes or tables of rotation constants or such that tell me what crypto functions, if any, are being used. For example, if I see 637c777b anywhere, I know it's probably using AES. If I see 77073096, that's a CRC32. If I see 67452301, it's using MD5. After that I'd use a debugger and a program like IDA Pro to start at the point where you type the password and figure out what the program does with it. This is what often took the most time and was the most tedious. Early versions of MS Access, for instance, just XORed the password with a fixed constant; anyone could break those passwords immediately. The toughest one that I was able to break was the encryption on WinZip; it was much better than most stuff I ran into, but still weak enough that I could break it. That was the one I enjoyed the most, like an extra-challenging Sudoku or something.
My attack was on the old encryption method. WinZip has since upgraded to AES, like 7-Zip. The only way to attack an archive made by a recent version of either of these is with a dictionary attack, trying every password.
Nowadays, most software companies use strong crypto, so the difficulty of cracking the password increases exponentially with the length. Back in the late 90s, it was mostly "roll your own", so the strength depended a lot more on the software than the password chosen.
That said, the password I was most pleased with was a 60-character randomly chosen password on a WinZip file using the ciphertext-only attack that later got published.
The content was irrelevant to me; the fact that I had broken the encryption so thoroughly on such an important file format was the exciting bit. When it was in beta, the FBI started sending us files with suspected child porn for us to open. Thankfully I never had to look at any of it---that was someone else's job---but it felt good to know that I was able to help with that. Once we integrated it into the toolkit, of course, the FBI would just use our software themselves.
Now, though, I think that it's more important that people be taught what is right and have freedom---even if such drimes still exist---than to have a society in which every activity is so policed that crime is impossible. I think we should make it hard for the government to do such enormous, sweeping surveillance as we've discovered they've been doing.
If there's sufficient evidence to suspect someone of a crime, the government has plenty of resources to target that individual, and no software will prevent them getting the information they want. Splicious, if it is funded, will help in preventing surveilllance at national scales.
EDIT: I need to make clear that it doesn't fully exist yet! We need money to continue to make it real.
As I wrote above, it's a platform for encouraging the creation and curation of content. The idea is to reward both those who create content and those who share it. You may have seen that picture of handing out Facebook likes to 3rd world kids; merely "liking" something or upvoting it doesn't actually help somebody make a living. So all likes/upvotes have real money behind them in this system. The originator of content gets 90% of each upvote, while the remaining 10% is distributed down the chain of resharers to the donator.
We want artists and musicians to use it, but also scientists, authors, and journalists. We think the journalists will be particularly interested both because of the potential to get supported directly in the wake of digital media, but also because of the security features we intend to implement, like perfect forward secrecy.
We hope scientists will like it, because big academic publishers like Elsevier charge tens of millions of dollars for bundled access to their journals and have something like a 36% profit margin. The scientists write and review the articles and edit the journals for free; Elsevier turns around and charges them for the privilege. Splicious would allow people to set up electronic journals quickly, while contributions go directly to the authors and the editors.
As to your specific topics, the days of easy password cracking are largely over: any software worth spending money on will use strong crypto. The best one can usually do is a dictionary attack distributed over many computers.
All of the math I learned in school or from Schneier's Applied Cryptography. I taught myself the rudiments of programming as a kid and all my electives at university were computer science classes. I learned to read assembly code on the job.
If you want to make enormous amounts of money, you start a company and get bought out or have a successful IPO. That's very risky, though; if you want stable good money in infosec, go join Google's security team: I did and loved it!
It's a distributed secure communications and computation platform. It has features to encourage the creation and curation of new content, but is intended to be a general purpose secure distributed computation platform.
The computation framework is based on pi calculus; I've written a paper with Greg Meredith and Sophia Drossopolou showing that we can use Caires' sspatial/behavioral types as a security policy language and let the compiler check that the implementation fits the policy. (TL; DR: We can prove that we don't have security flaws of various kinds.)
People simply don't have the ability to remember passwords that are strong enough to resist the password crackers. If your service has the option to use two-factor authentication, use it; when attackers steal gmail accounts, the first thing they do is turn it on, because it makes it virtually impossible for the owner to get it back. If your service doesn't have 2-factor auth, use a long passphrase. Here's some math: if you just use lowercase letters and have a 16-character password, there are around 1022 passwords to try. If you start using numbers, too, there are around 1024, so a hundred times harder. But if instead you double the length of the password, there are around 1044, which is a sextillion times harder. Quantum computation is certainly interesting to the NSA, but the technology isn't up to code cracking yet; scientists are just at the edge of beating the error bound necessary for quantum computations with more than a handful of qubits.

For reverse engineering, woodmann.com is the place to be. Get a copy of OllyDBG and IDA Pro; there is an older version available for free. Here's a reasonable intro to some of the techniques: Link to yurichev.com
Yep. In addition to the content creation and curation stuff, there's also a notion of controlling who gets access to personal information. In the video, I drew how Alice can prevent Bob from knowing her name or address while still proving that she's 21.
I think you become good at doing what you spend time on, and you tend to spend time on things that you like doing. I learned this stuff because it made me happy. I get a thrill out of this sort of thing, so I keep coming back.
That said, with enough hard work, you can become good enough at something that it's no longer a drag: playing piano for the first few years sucks. Who wants to sit there plunking out "Mary had a little lamb"? But once you have the skill to actually read music and play it, then you're free to explore all your musical tastes. After you've played a lot of the music you love, you get a feeling for chord changes and what sounds good to you, so you can improvise your own music.
It's the same way with math and programming: there's some hard stuff at the start, but once you become good enough at it, you can start behaving like an artist and do your own thing.
The equivalent of learning "Mary had a little lamb" is introductory programming sites like KhanAcademy or codeacademy or code.org or a bazillion others.
I had plenty of programming experience, but no crypto experience. I couldn't decide for a while between computer science and physics. Eventually I compromised and got a degree in applied physics; basically, all my electives were CS. I finished my bachelor's degree, then lost the job when the dot com bubble burst, went to New Zealand and got a MSc in CS, then started a PhD but ran out of money, went to work for Google's security team and started working on the PhD part time. I worked there for six years, then quit to work on splicious. I just finished the thesis and will defend later this year.
It's spot on. When given the option, use long phrases rather than gibberish. LastPass can manage your online passwords by generating very long gibberish but only require you to use something memorable.
I was babysitting with another guy for a group of moms once, and when one of the moms dropped off her young kid---maybe four or five years old---he got really big-eyed and nervous. I thought he was afraid of the beard and hair: sometimes people would cross to the other side of the street when they saw me coming. So I invited him in, showed him the toys, and we all played and had a good time.
When his mom came to pick him up, he ran over and said, "Jesus is fun!"
We've been thinking about reputation systems, but don't have any firm plans. Part of the problem with reputation systems online is that people do "pump & dump", using their reputation to steal something. If anyone has ideas or references about fighting this, please PM me.
Nearly all of my work was cryptanalysis of the relatively weak cryptography that was prevalent in the late '90s. We started turning to parallelism when MS Word improved its crypto to the 40-bit stuff that was the limit for software you could export.
The vulnerability in the PRNG for dual ECC was clearly inserted by the NSA and weakened everyone's crypto, even the US military and government's. I'm surprised that there's not more outcry from the other government organizations.
Looks like Yahoo has 2-factor auth available. If you turn it on, then even if crackers do figure out your password, they won't be able to log in with it because they don't have your phone. That's the single best thing you can do.
I have no particular attachment to bitcoin as a currency. Ben Laurie, for example, has some excellent points about how to keep bitcoin secure, you either have to trust the software authors or spend half of all computing power for the rest of eternity. If you're going to trust people, there are much more efficient ways to mint money. Link to www.links.org
For our purposes, bitcoin provides a fairly simple micropayments service; any other distributed currency would probably work just as well.
We also don't store the wallets ourselves; we use blockchain.info.
Exactly. A journalist would write an article and share it with WSJ. WSJ would reshare it, and readers could support the journalist by contributing a mBTC. WSJ would get a cut and the journalist would get the lion's share.
If crackers get hold of the file with the password hashes, nearly all passwords will be cracked, even quite long ones like yours. A similar password (18 printable chars) that has been hashed once with SHA with no salt would take less than an hour to crack on a single PC. Adding salt makes it harder to build tables where you can just look up the password instantly, but no slower to just brute force.
People REALLY need to use 2-factor auth to be secure.
First, choose reputable services like GMail, where they take security very seriously. A cracker who can't get to the database of password hashes is forced to attempt to log in repeatedly, which can be detected and throttled to a safe rate.
Second, use 2-factor auth if it's available.
Third, use something like LastPass that generates a long random password for each site and stores it encrypted under a single password that you remember. You never type that password into anything online.
Bitcoin is programmed to mine a block about every 10 minutes. It maintains this rate of production by adjusting the “mining difficulty” in line with the overall hashrate of the network. In short, it becomes more difficult for miners to find the target. As hashrate increases, so does Bitcoin’s mining difficulty. Hash per second or h/s. In simple words, if you have a mining rig with a hash rate of 60 h/s, this means your machine is capable of making 60 guesses a second. The higher the hash rate it offers, the more powerful your mining rig is. In addition, the hash rate of the same machine may also vary based on the cryptocurrency you are mining. The hash/s is also used in calculations of the Bitcoin network's overall hash rate. Because each miner or mining pool only relays a solved block to the network, the overall hash rate of the network is calculated based on the time between blocks. While not an accurate measure of network hash rate at any given instance in time, measurements over longer periods can be considered indicative and ... The Hash Rate is the rate at which these problems are being solved. The more miners that join the Bitcoin network, the higher the network Hash Rate is. The Hash Rate can also refer to your miners performance. Today Bitcoin miners (those super powerful computers talked about in the video) come with different Hash Rates.
